You're pretty good

During phase 3 (MGS3: Snake Eater phase) of the Ocelot battle, Ocelot may try to grab and choke snake at some point. Press nothing at all when the left control stick prompt appears, and Ocelot will kiss Snake afterwards.

Your best bet to initiate this is to stay away from the pillars (which will change Ocelot's attack to pounding you against a pillar), and to tap R1 once per attack. This usually triggers Ocelot trying to grab Snake in some form, you just need to hope for the left stick prompt.
